GAS-=ENGINE.

SPECIFICATION forming part of Letters Fatent NO. 547,414, dated October8, 1895. Application filed February 3,1894- Serial No. 498,943. (Nomodel.)

To aZZ whom it may concern.-

Beit known that I, JOHN J. BORDMAN, a citizen of the United States ofAmerica, and a resident of Brooklyn, in the county of Kings and State ofNew York, have invented new and useful Improvements in Gas-Engines, ofwhich the following is a specification.

This invention relates to that class of engines in which anexplosive-gas is employed, and it comprises a turbine-wheel operating toopen and close the gas and air ports and to receive the impulse of theexplosive-xnixture.

I will describe an engine embodying myinvention, and then point out thenovel features in appended claims.

In the accompanying drawings, Figure l is an elevation, partly insection, of an engine embodying my invention. Fig. 2 is a longitudinalcentral section thereof. Fig. 3 is a transverse vertical section,showing a modified arrangement of ports. Fig. 4 is an elevation, partlyin section, showing a modification. Fig. 5 is an end view of theignitingchamber, showing a part of the igniting mechanism. Fig. 6 is across-section thereof. Fig. 7 is an elevation, partly in section,showing a modification. Fig. 8 is a transverse section thereof. Fig. 9shows a mechanism for modifying the speed of the power-transmittingshaft, and Fig. 10 is a side elevation thereof.

Referring by reference-characters to the drawings, A designates acylindrical casing, supported by a suitable base and comprising anannular explosion-chamber a, an annular water-jacket a, and the interiorchamber a within which the powerwheel B rotates. Water is supplied tothe jacket through the passage n, circulates through n 72 and dischargesthrough n This power-wheel Bis rigidly mounted on a power-shaft a havingbearings through the end walls B of the cats ing A, and provided with afly-wheel D and a band-wheel or pulley E.

The power-wheel B is provided in its periphery with buckets b, the endwalls of which extend substantially at right angles to the axis of thewheel and are designed to receive the shock or force of the explodinggas which passes from the explosion-chamber a into the buckets throughports f, extended through the water-jacket a. The ports fare shown asarranged ata tangent, so that the force of the explosion will be moredirect upon the walls ofthe buckets. The walls of the ports fdo notextend entirely across the waterjacket, but spaces or openings are leftat the ends for the free circulation of water, as shown at d in Fig. 2.The water-jacket a not only extends around the inner circumference ofthe explosion-chamber, but extends over the outer side thereof, asplainlyshown in Fig. 2. This water-jacket obviously serves to prevent anover-heating of the parts coming in contact with the exploding gas.

The wheel B has blade-like spokes 1), extending from the hub c to therim or pocket portion, and these spokes, with the end walls 19 form thegas and air mixing chambers. Atmospheric air passes into the spaces orchambers between the blades or spokes through holes 7c in the casing A,and if desired the flow of air may be regulated by means of a damper(shown in Fig. 2) in the form of an annulus B mounted to rotate on abearing of the shaft a and provided with openings that may register moreor less with the holes 10. Some or all of the blades or spokes b may beprovided with openings'k for the more thorough circulation and mixtureof the gas and air.

I will now describe means for supplying gas to the engine.

B indicates a tank or receptacle for containing a supply of gasoline orother hydrocarbon, and this tank has a valve-controlled conduit 6communicating withalongitudinal hollow or chamber in the shaft of, whichat its inner end has a series of outlets 19 opening into the spacecontaining the blades or spokes of the wheel. In order to govern theinflow of gas, and therefore govern or render uniform the speed of theengine, I provide a valve to open or close more or less the openings 19As shown in Fig. 2, this valve consists of a plug or piston B adapted toslide longitudinally in the bore of the shaft a It has connection with arod b extending through the shaft and having pivotal connection at theouter end with fulcrumed weighted arms B which by centrifugal actionserve to move the rod b and consequently the valve 13. The concave diskB centrifugally diffuses a liquid, as gasoline, issuing from outlets 11The gasoline issues from the openings b in the form of a spray or vaporby centrifugal action or by the suction of the wheel B and becomesthoroughly mixed with the air. This explosive mixture passes from thespaces or chambers between the blades or spokes to theexplosion-chamber, through ports h in the end walls 19 through ports h,communicating with radial channelsj, formed in the end walls B of thecasing A, and through ports h which communicate with theexplosion-chamber a. In other words, the blade-like spokes of thepower'wheel serve the purpose of an exhaust-fan, drawing the air and gasinto the wheel and by centrifugal force the mixed air and gas is driventhrough the ports communicating with the explosion chamber. It will beseen that the end walls b of the wheel B serve as a valve to cut on. andopen the flow of gas and air to the explosion-chamber and that theperipheral face of the wheel B adjacent the brackets I) serve asacut-off valve for the ports f. An exhaust-passage (2 leads from thepockets 1) to any outlet 6 for the discharge of the products ofcombustion.

I will now describe means for igniting the gas in the explosion-chamber.

C designates pole-pieces having bearings of insulating material 0 andhaving electrical connection with any desired source of electricitysuch,for instance, as a battery 0. The pole-pieces have a yieldinglongitudinal movement, and for this purpose I employ springs c, abuttingat one end against collars or shoulders on the pole-pieces and at theother end against a fixed portion of the easing, as shown in Fig. 2.

O designates contact-pieces adapted to make and break connection withthe polepieces. These contact-pieces are mounted on a carrier 0 whichhas rotary motion imparted to it from the shaft e As shown in Fig. 2,this carrier is mounted on the inner end of shaft 0 having an insulatedbearing in the casing and provided at its outer end with a bevel-gear cmeshing with a bevel-gear c on a shaft 0. The opposite of the shaft 0has a bevel-gear c", engaging with a gear-wheel c rigidly mounted on theshaft a The contact-pieces O and the pole-pieces O are arranged to makeand break electrical connection within a chamber 0 having communicationwith the explosion -chamber a, and the rotary movement of thecontactpieces is so timed that the are or sparking will take place whentheexplosion-chamber is filled with explosive and the several ports itare closed and the several ports or jet'passagesf are uncovered at theirinner ends.

In the example of my improvement shown in Fi 3 there are but twogas-ports leading into the explosion-chamber, and it will be seen thatthe ports h are arranged in different circles and that the ports h arealso arranged in different circles, so that said chamber is charged withgas but once during an entire revolution of the power-wheel, and toproperly time the igniting mechanism I have shown the carrier for thecontact-pieces as rotated from the shaft a by means of a sprocket-chainD and the sprocket-wheels D D.

In the example shown in Fig. 4 I have shown a water-jacket d assurrounding the outer side of the explosion-chamber.

In the modification, Figs. 5 and 6, I have shown the contact-pieces madein the for-m of a yoke 01, which has insulated connections with thecarrier 0 In lieu of the several buckets heretofore described for thepower-wheel I may employtwo buckets for the gas explosion, as shown at Ein Figs. '7 and 8, and the faces of these buckets may be concaved, asshown. In this example I use jet-tubes f, projected through bearingsthrough the water-jacket, and the casing A may have plug-stoppedopenings f opposite the jet-tubesf, so that said jet-tubes may be easilyinserted or removed when desired. In this example the exhaust or spentgases pass through lateral ports F into an annular passage F formed inthe casing and having an outlet 6.

In Figs. 9 and 10 I have shown means for reducing the speed of thedriving-pulley E. In this device the driving-shaft is made in twosections G G,the section G having hearings in the casing A and thesection G having a bearing in a pillow-block G On the section G of theshaft is affixed a crank D, which may be in the form of a fly-wheel orarm. A pin 1 extends from the crank D and a double pinion 2 isrotarilymounted on this pin. The crank may have a weight 3 attached toit to counterbalance the double pinion 2. One section of the doublepinion 2 meshes with a gearwheel 4, mounted in a fixed position on thepillow-block G and the other portion of the double pinion meshes with agear-wheel 5 fixed on the section G of the driving-shaft. The pinion 2,in rolling around the fixed gear 4, is caused to rotate on its pin andimpart rotary motion to the gear 5 and section G of the shaft, when gear5 has a greater or less number of teeth than gear 4. For example, gear 4may have one hundred teeth and gear 5 one hundred and one teeth Thepinion having ten teeth, in rolling around gear 4, will revolve on itspin ten times, and in rolling around gear 5 impart a movement or speedrelatively to gear 4, equal to one tooth, or the difference between thenumbers of teeth of the two gear-wheels.
